Hey! I started a Clan for Extinction called Kryptid, for Extinction players of course. It's mainly for the Hardcore Extinction players. If you would like to join, you'd have to be willing to change their GamerTag to Kryptid Something.. Ex. My GT is Kryptid Slayer. If you would like to join, or anything, or even just play. Message me.
Xbox One players ONLY by the way.
I can get how they change the gamertag if your in a well known clan or if you participated in a tournament with a clan but changing it for extinction just seems a little odd to me.
